OLIVER COLE AND OLIVER K. COLE, OF TURNER, OREG-ON.

FLOUR-SIFTER.

SPECIFICATION forming part of Letters Patent No. 780,706, dated January24, 1905.

Application filed April 13,1904. Serial No. 203,004.

T0 all whom, t may concern:

Be it known that we, OLIVER G. COLE and OLIVER K. COLE, citizens of theUnited States, residing at Turner, in the county of Marion and State ofOregon, have invented certain new and useful Improvements inFlour-Sifters, of which the following is a specification.

This invention provides a simple and cheap construction of iiour-sifterparticularly adapted for home use for sifting the flour in smallquantities. u

The essential feature of the invention resides in a peculiar form ofagitating device mounted within the sifter which facilitates the siftingoperation,therefore increasing the g eneral desirability of the article.V l

The sifter is designed to be used also. in the capacity of afruit-strainer, being of a construction suitable for said purposes, aswill be more fully noted hereinafter.

For a full description of the invention and the merits thereof andalsoto acquire a knowledge of the details of construction of the meansY foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modiiication, still the preferred embodiment of the4invention is illustrated in the accompanying drawings, in which` Figure1 is a vertical sectional view through a flour-sifter embodying ourinvention. Fig. 2 is a top plan view.k Fig. 3 is a detail perspectiveviewof the agitating means, bringing out more clearly the exactconstruction of this part.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samreference characters.

In general form our sifter is substantially the same as are those now incommon use, b eing of a size sufficient to hold enough flourfor ordinarybaking purposes. The invention comprises the receptacle or cylinder l,which receives the flour, anda handle 2 projects laterally from thecylinder, the latter being grasped in supporting the sifter when inoperation. The sifting sieve or screen 3 is rearticle to no smallextent.

movably applied to the receptacle l, being carried by a ring or likeannular member 4, which latter is detachably secured to the lower porjtion of the said receptacle 1. The sieve or screen 3 is attachedto thering 4: in any suitable manner and is preferably of flat form. Lugs 5are projected laterally from the lower portions of the receptacle 1, andthese lugs are adapted to be engaged with angular grooves 6, formed inthe ring 4C, in securing the latter in position upon the receptacle.

The peculiar form of agitating device utilized in our invention, whichis specially constructed witha view to vquickly sifting the iiour, iscom posed of horizontally-disposed dia strip provided withdownwardly-extending vergeht arms 7, each of which is composed ofvertical flanges or flights 8. Ihe iianges or flightsV 8 are integralwith the arms 7 and are `formed by bending the edge portions of said.arms longitudinally thereof.

readily admit of formation of the downwardlyprojecting scraping flangesor members 8. The formation of the arms admits of a verycheapconstruction of agitating device, Which cheapens the general cost of theThe agitating device rests directly upon the sieve or screen 3, and thescraping-flanges 8 directly engage the said screen in the operation ofthe sifter.-

The agitating device is rotated in the sifting operation by means of acrank-shaft lO,

which latter is suitably connected with the IOO jected inwardly from thesides of the receptacle l. A lower arm l1b also connects the handle 2with the receptacle 1, An operatinghandle 12 is mounted upon the upperend of the crank-shaft 10, and this part is manipulated in sifting thefiour in a manner which will be readily apparent to those cognizant withthis part of the invention.

The removable sieve or screen structure is especially useful .forcleaning purposes, particularly when the device is utilized as afruitstrainer. When it is desired to clean the agitating device or thesieve proper, it is only requisite to detach the ring 4 by a slightrotary movement thereof, and ready access may be thus had to the severalinterior parts.

The divergent arms 7 are connected at their outer ends by an annular rim14, which is integrally formed with the arms, being stamped from thesame metallic blank that the scraping device is produced from. The rim14 lends a greater rigidity to the divergent arms 7 in a manner whichwill be readily seen, greatly strengthening these arms in the practicaloperation of the agitating device.

Having thus described the invention, what is claimed as new is- Incombination, a screen, an agitator comprising a central portion, a ringconcentric therewith, arms between said central portion and ring andhaving their longitudinal edge portions bent about at a right angle tothe plane of the agitator toward the screen to forni iights, and anoperating-shaft attached to the central portion of the agitator,substantially as Speciied.

In testimony whereof we aflx our signatures in presence of twowitnesses.
